The Chrome and Safari teams have chosen not to display approximate
progress bars for user interface design reasons.
You can implement a progress bar for a WebKit-based browser by using
the -estimatedProgress method in WebView.h and the associated
notifications WebViewProgressStartedNotification,
WebViewProgressEstimateChangedNotification, and
WebViewProgressFinishedNotification.
Note that any such progress bar (in any web browser, WebKit-based or
not) is only an approximation, because as a page loads resources, it
might discover additional resources that need to be loaded, so the
page cannot know in advance how much more there is to load.

I took a look at all the ViewMsg and ViewHostMsg in Chrome's src,
and didn't find anything related.
So, is that unimpossible to create such a progress bar?
If it's not so hard, how to achieve that?
